Abstract

Tumors of the optic nerve are mostly either optic nerve gliomas/optic nerve sheath meningiomas. While gliomas occur in children, most meningiomas are slow-growing tumors affecting middle-aged individuals with progressive visual loss, proptosis, disc edema and optociliary veins on fundus examination.
Purpose – To study the growth of optic nerve sheath meningiomas and evaluate their management outcome.
Methods and materials – A 38-year-old male with left sided exophthalmos presented to RIO, GMCH. Patient complains of diminution of vision of left eye and protrusion of the left eyeball for last 6 months. Ophthalmological and endocrinological clinical examination as well as laboratory tests revealed no pathology from optic nerve disc, optic bulb and thyroid related hormones. CEMRI study demonstrated an optic nerve meningioma. The key imaging findings and management will be discussed.
Conclusion – Radiotherapy is indicated in patients with progressive visual deterioration.
